Radiating leg pain is common in patients with low back pain (LBP). In this study, we aimed to determine the prevalence and incidence of LBP with radiating leg pain in Dutch general practice, and to describe the prescribed medications and requested imaging diagnostics. ⋯ In this new study, we have gained insights into the incidence and prevalence of LBP with radiating leg pain in Dutch general practice. Both remained fairly stable over the study period of 9 years (2013-2021). Overall, the care burden regarding seeking contact with the GPs and the requested diagnostics seem not to be that high. In 62% of the care episodes, there were one or two consultations with the GP, and in 11% of the episodes a diagnostic imaging was requested. Pain medications frequently prescribed (i.e. 2/3rd of the episodes), with NSAIDs being the most common ones.

Some patients with back pain contribute disproportionately to high healthcare costs; however, characteristics of high-cost users with back pain are not well defined. We described high-cost healthcare users based on total costs among a population-based cohort of adults with back pain within the Ontario government's single-payer health system across sociodemographic, health, and behavioural characteristics. We conducted a population-based cohort study of Ontario adult (aged 18 years or older) respondents of the Canadian Community Health Survey (CCHS) with back pain (2003-2012), linked to administrative data (n = 36,605; weighted n = 2,076,937, representative of Ontario). ⋯ High-cost users tended to be current/former smokers, obese, and report fair/poor mental health. High-cost users (based on total costs) among adults with back pain account for nearly half of all healthcare spending over a 1-year period and are associated with older age, lower income, comorbidities, and fair/poor general health. Findings identify characteristics associated with a high-risk group for back pain to inform healthcare and public health strategies that target upstream determinants.

Workplace attitudes among nurses with back pain disability are usually unsupportive as nurses tend to rely on passive approaches like pain medications and taking sick leave to manage the impact of their back pain experiences. ⋯ The 14 messages on back pain given to the participants were reviewed to enhance clarity, applicability, and acceptability. Messages with similar meanings were merged, reducing the total number to 7. The revisions made to the 14 back pain messages aimed to improve understanding, acceptability, and relevance within the contexts and circumstances in which nurses' practice. This is important because the messages adapted for use in low- and middle-income countries like Zambia are equivalent and applicable to those originally developed in high-income countries.

In humans and animals, high-frequency electrocutaneous stimulation (HFS) induces an "early long-term potentiation-like" sensitisation, where synaptic plasticity is underpinned by an ill-defined interaction between peripheral input and central modulatory processes. The relative contributions of these processes to the initial pain or nociceptive response likely differ from those that underpin development of the heightened response. ⋯ Application of a distant noxious conditioning stimulus during HFS did not alter perceived primary or secondary hyperalgesia in humans or the development of primary or secondary neuronal hyperexcitability in rats compared with HFS alone, suggesting that, upon HFS-response initiation in a healthy nervous system, excitatory signalling escapes inhibitory control. Therefore, in this model, dampening facilitatory mechanisms rather than augmenting top-down inhibitions could prevent pain development.
